Abstract

The present disclosure provides adhesive mounting articles that can be removed from surfaces without damage by having reduced contribution of a hardgood to the peel force generated by the adhesive article during removal. In some instances, this can be accomplished by a hardgood that is flexible in a peel direction and rigid in a weight hanging direction. Such hardgoods may include a plurality of minimally connected body segments arranged about the transverse axis of the hardgood body.

First claim

We claim:

1. A flexible article for use with a pressure-sensitive adhesive layer in mounting an object to a surface, the flexible article comprising:
a flexible molded body with a longitudinal direction and a transverse direction and a frontward side and a rearward side and having a plurality of discrete body segments arranged at a defined pitch, wherein the flexible molded body is more rigid in the longitudinal direction than in the transverse direction, and
a flexible backplate that has a frontward major face and a rearward major face, that is located on the rearward side of the flexible molded body, and that is a molded backplate that is monolithic with the flexible molded body, and wherein the rearward major surface of the flexible molded backplate is configured to have a pressure-sensitive adhesive layer affixed thereto,
wherein the discrete body segments are elongate with a long axis that is at least generally aligned with the longitudinal direction of the flexible molded body and wherein each discrete body segment comprises a rearward face, the rearward faces of the discrete body segments being in integral contact with areas of the frontward major face of the flexible molded backplate,
and
wherein the flexible molded body comprises a frontwardly-extending mounting projection that is a molded mounting projection that is monolithic with the flexible molded body and that is provided by at least one discrete mounting segment, the at least one discrete mounting segment extending frontwardly from a respective discrete body segment and being elongate with the at least one discrete mounting segment having a long axis that is at least generally aligned with the longitudinal direction of the flexible molded body.

2. The flexible article of claim 1 , wherein each discrete body segment of the plurality of discrete body segments includes a linear segment and wherein all of the linear segments of the discrete body segments are arranged in parallel to one another.

3. The flexible article of claim 1 , wherein the frontwardly-extending mounting projection defines a recess between the frontwardly-extending mounting projection and the discrete body segments, the recess being closed-ended at a lower end of the recess and open-ended at an upper end of the recess.

4. The flexible article of claim 1 , wherein the at least one discrete mounting segment is in the shape of a hook.

5. The flexible article of claim 1 , wherein the discrete body segments are oriented perpendicular to the transverse direction of the flexible molded body.

6. The flexible article of claim 1 , wherein the discrete body segments each exhibit a length to width ratio of at least 15:1.

7. The flexible article of claim 1 , wherein the discrete body segments are spaced at a uniform pitch along the transverse direction of the flexible molded body.

8. The flexible article of claim 1 , wherein the discrete body segments each exhibit a thickness, in a frontward-rearward direction of the flexible molded body, that varies along the longitudinal direction of the flexible molded body, with the thickness being smaller toward longitudinal edges of the flexible molded body and being greater toward a longitudinal center of the flexible molded body.

9. The flexible article of claim 1 , wherein the discrete body segments exhibit a thickness and wherein the flexible molded backplate exhibits a thickness, both thicknesses being in a frontward-rearward direction of the molded body and of the backplate, and wherein the thickness of the flexible molded backplate is less than the thickness of the discrete body segments.

10. The flexible article of claim 1 , wherein at least one of the discrete body segments comprises an end that is integrally, directly connected to an end of an adjacent discrete body segment by way of a backplate portion that is between, and is integrally connected to, the end of the discrete body segment and the end of the adjacent discrete body segment.

11. The flexible article of claim 1 , wherein at least some discrete body segments of the plurality of discrete body segments each comprise an end that is integrally, directly connected to an end of an adjacent discrete body segment by way of a backplate portion that is between, and is integrally connected to, the end of the discrete body segment and the end of the adjacent discrete body segment.

12. The flexible article of claim 11 , wherein at least some of the discrete body segments each comprise an end that is not directly connected to any nearest-neighbor end of any discrete body segment other than by way of a backplate portion that is between, and is integrally connected to, the end of the discrete body segment and the nearest-neighbor end of the adjacent discrete body segment.

13. The flexible article of claim 1 , wherein the discrete body segments are exposed discrete body segments that are not buried or encapsulated within the flexible molded backplate or within any other item.

14. The flexible article of claim 1 , wherein the at least one discrete mounting segment is elongate with the long axis of the at least one discrete mounting segment being oriented at least generally along the longitudinal direction of the flexible molded body.

15. The flexible article of claim 1 , wherein the rearward faces of the discrete body segments collectively define a common plane that is in integral contact with the areas of the frontward major face of the flexible molded backplate.

16. The flexible article of claim 1 , wherein the at least one discrete mounting segment comprises a linear portion with a long axis that is aligned with the longitudinal direction of the flexible molded body, and wherein the linear portion of the at least one discrete mounting segment terminates at an upper end that defines an upper end of the at least one discrete mounting segment and that defines an upper end of the frontwardly-extending mounting projection.

17. The flexible article of claim 1 , wherein the at least one discrete mounting segment comprises a rearward face that defines a plane that is aligned parallel with a common plane collectively defined by rearward faces of the discrete body segments.

18. The flexible article of claim 1 , wherein the at least one discrete mounting segment defines a recess between the frontwardly-extending mounting projection and the discrete body segments, with the recess exhibiting a frontward-rearward gap between a rearward face of the at least one discrete mounting segments and frontward faces of the discrete body segments.

19. An adhesive article comprising the flexible article of claim 1 with a pressure-sensitive adhesive layer affixed to the rearward major surface of the flexible molded backplate of the flexible article.

20. The adhesive article of claim 19 wherein the pressure-sensitive adhesive layer is a peelable pressure-sensitive adhesive layer.

21. The adhesive article of claim 19 wherein the pressure-sensitive adhesive layer is a stretch-releasable pressure-sensitive adhesive layer.

22. A kit comprising at least one flexible article of claim 1 along with at least one pressure-sensitive adhesive.

23. The kit of claim 22 wherein the pressure-sensitive adhesive is a peelable pressure-sensitive adhesive.

24. The kit of claim 22 wherein the pressure-sensitive adhesive is a stretch-releasable pressure-sensitive adhesive.
